I was working on a simple spring op like that for secondary motion as well (in Python though). I’m playing around with your’s to see if it could help me get further as I’m trying to make mine able to resume default state when it’s going at a constant speed in the same direction (same velocity). I didn’t think of adding a wind, nor a gravity like your’s. Very nice addition! It may well be the answer I was looking for. :)

thanks, Richard…still having an issue just installing it via File->Add-on->Install (I can find the addon,
but the ‘install’ button is greyed-out)…if I install by just dragging into viewport, it shows up as an installed addon, but the MindThink toolbar doesn’t exist for me to even access. Never had a problem installing 3DQuakers or squid’s UVLayout plugins…prolly some newb error on my part tho. Will keep trying.

Hi there,
THanks so much for this cool tool!
One question however, once you have created the spring objects, is it possible to adjust the point they pivot around in order to fit it to my rig? I understand there is the option to scale the chain elements but the first bone doesn’t seem to pivot from the center of the first null.

what glorious fun this is.
im going to attempt to assign it to a bunch of preexisting bones, or perhaps just read positions/ rotations and bone lengths from preexisting bones.
thanks helge, Its fantastic to see things like this done with production in mind.

Hi
Im using the mt spring op for the first time, works great, very quick and simple.
but i cant seem to get mirrored sym. The method i use works but gives different dyn result for each side, (i duplicated my null, with Shared parrent on, & freeze negative scale off, then set neutral pose for the duplicated ob.., then created springs) is this wrong.
ps i need to get this duplicate sym work today if posible for this project.
can any one HELP!!!!!!!!!!!!
Thanks

i ve been using the spring for a while and i found something strange. The parameters sometimes will all disappear except size and length……well, the spring is still working but i cant adjust the parameters any more. The only solution is to redo the settings…
Do you know why this is happening and any way to show back the parameters?
